Answer:
Step-by-step explanation:
you have to use the midpoint formula which is
so you plug your numbers in
Add the tops
if possible simplify
and that is your answer
B because both lines a and b are parallel which makes 1 and 9 congruent
Answer:
y=15
Step-by-step explanation:
The formula for direct variation is
y = kx
5 =k*2
Solve for k
Divide by 2
5/2 = k
y = 5/2 x
Now we substitute x=6
y = 5/2(6)
y = 15
Answer:
36
Step-by-step explanation:
i) first you combine the like terms; 3x² and x², then 4x and -8x, then -7n and -1.
Then you would get 4x²-4x-8.
You then cannot simplify further. so your answer would be 4x²-4x-8.
